Product Overview

The DS1307+ is a 64 x 8, serial, I2C real-time clock (RTC) in 8 pin PDIP package. The serial RTC is a low power, full binary-coded decimal (BCD) clock/calendar plus 56bytes of NV SRAM. Address and data are transferred serially through an I2C, bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, month and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator. It has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. The timekeeping operation continues while the part operates from the backup supply.
  • Supply voltage range is 4.5V to 5.5V
  • Operating temperature range from 0°C to 70°C
  • Manages all timekeeping functions, 56byte, battery backed, general purpose RAM with unlimited writes
  • Programmable square-wave output signal
  • Simple serial port interfaces to most microcontrollers, I2C serial interface
  • Low power operation extends battery backup run time
  • Consumes less than 500nA in battery backup mode with oscillator running
  • Automatic power-fail detect and switch circuitry
  • Maximum standby current is 200µA
  • UL recognized
